PC板的內應力構成于擠出成型及冷卻定型的過程中,而在PC板的外形基本上沒發作任何改動的放置或許運用過程中,將經歷一個應力松懈效果,有些的消除可一些內應力。可是只是經歷有限的松懈的PC板很難徹底消除這些應力,再其內留有應力,假定在運用過程中不注意增大外在的應力,將會發作面層的有些變形而且接近于外表而從此處于現易破點(纖細的開裂、裂紋)。因而,咱們在運用中有必要防止那些不正確的或許過火的外部應力
PC board of internal stress in the process of extrusion and cooling to finalize the design, and the appearance of the PC board basically didn't attack the placement of any changes may use in the process, will experience a stress lax effect, some eliminate to some internal stress. But only limited experience lax PC board is very difficult to eliminate the stress, stress, which have assumed in use do not pay attention to during the process of increasing external stress, surface will attack and close to the appearance of some deformation and from then on is now easy to break point (fine crack, crack). Therefore, we in the use of it is necessary to prevent the incorrect perhaps far external stress
致使PC板材開裂的要素有許多，主要和板材的方案、選材、施工等方面的聯絡比較大。假定方案不合理，選材不正確，或許是在施工的過程中沒有做好一些很細節的方面，都會致使PC板材開裂。
Led to many PC plank crack elements, the main sheet and the methods, materials, construction and other aspects of the contact is larger. Assume that plan is not reasonable, select material is not correct, may be in the process of construction was not well done some very details, will cause the PC board crack.
假定PC板材放置的環境過火濕潤或許單調都會有欠好的影響，過于濕潤會發作脹大，過于單調又會發作縮短，這么最簡略致使PC板材開裂了，關于這些疑問，咱們處理的辦法有：
Assume that humid environment of the PC board placed far maybe monotonous will have owe good, too wet will attack swell, too monotonous and can shorten, so the brief that PC plate cracking, about these questions, let's processing method are:
能夠運用機械的辦法，強行PC板材呈現脹大或許縮短；
Able to use mechanical approach, forced swell may shorten the PC board presented;
在木材加工的過程中，能夠改動加工的辦法，防止呈現開裂的景象；
In the process of wood processing, can change the processing method, prevent craze of rendering;
在PC板材的兩頭和外表涂上防水涂料，這么能夠下降木材外表的蒸騰濕度，削減木材開裂的程度；
At the two ends of the PC board coated with waterproof coating and appearance, so can lower transpiration humidity appearance of wood, cut wood craze degree;
對木材進行高溫處理，削減開裂的概率；
Heat treatment of wood, cut down the probability of cracking;
運用防水劑，這么能夠做好防水處理，就不會呈現開裂的狀況了。
Using the waterproofing agent, so can good waterproof processing, will not be presented the status of the cracking.
